PROBLEM TO BE SOLVED: To provide an eccentric oscillation type gear device which can be thinned with a simple structure.SOLUTION: An eccentric oscillation type gear device 10 includes: an outer cylinder 12 which has a plurality of inner teeth on the inner circumferential surface; an eccentric part 20b; an oscillating gear 18 having an insertion hole to which the eccentric part 20b is inserted, being engaged with the inner teeth in conjugation with the rotation of the eccentric part 20b and, at the same time, being rotated in the outer cylinder; a carrier 14 which has a bolt insertion hole 14c penetrating in the thickness direction, is fixed to a fixation objective member 70 by a bolt screwed to the bolt insertion hole 14c and is relatively rotated with respect to the outer cylinder 12 because rotation of the oscillating gear 18 is transmitted; and a closing member 60 which closes an opening part 14d of the bolt insertion hole 14c. |
